Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with around 100s left on the timer, others might run out of time on their first try.
These super mario world giant pipes were made by me, I adapted the super mario world pipes to be giant on map 8, compatible with piranha plants from Imamelia and giant piranha plants from Davros and Mikey, custom venus from Imamelia, credit is optional. These pipes were inspired by the Hammer Brother pipes.

Sadly, this graphic can't be approved due to some reasons.
First is that it only includes very few giant objects like pipes, clouds and sideways pipes. This space could be way better optimized. Also, the pipes and other objects are clearly upscaled and so they look rough around the edges. For bigger objects, it's always good to offer a good shading and trying to make them look smoother.
Second thing, the submission is missing map 16 and sample level. Do not resubmit until you fix all the issues. Also, this tileset lacks variety, so you will need a lot of work and patience to do a very nice tileset. Good luck.
